| * Qualcomm Technologies APQ8096 ASoC sound card driver |
| |
| This binding describes the APQ8096 sound card, which uses qdsp for audio. |
| |
| - compatible: |
| Usage: required |
| Value type: <stringlist> |
| Definition: must be "qcom,apq8096-sndcard" |
| |
| - qcom,audio-routing: |
| Usage: Optional |
| Value type: <stringlist> |
| Definition: A list of the connections between audio components. |
| Each entry is a pair of strings, the first being the |
| connection's sink, the second being the connection's |
| source. Valid names could be power supplies, MicBias |
| of codec and the jacks on the board: |
| Valid names include: |
| |
| Board Connectors: |
| "Headphone Left" |
| "Headphone Right" |
| "Earphone" |
| "Line Out1" |
| "Line Out2" |
| "Line Out3" |
| "Line Out4" |
| "Analog Mic1" |
| "Analog Mic2" |
| "Analog Mic3" |
| "Analog Mic4" |
| "Analog Mic5" |
| "Analog Mic6" |
| "Digital Mic2" |
| "Digital Mic3" |
| |
| Audio pins and MicBias on WCD9335 Codec: |
| "MIC_BIAS1" |
| "MIC_BIAS2" |
| "MIC_BIAS3" |
| "MIC_BIAS4" |
| "AMIC1" |
| "AMIC2" |
| "AMIC3" |
| "AMIC4" |
| "AMIC5" |
| "AMIC6" |
| "AMIC6" |
| "DMIC1" |
| "DMIC2" |
| "DMIC3" |
| = dailinks |
| Each subnode of sndcard represents either a dailink, and subnodes of each |
| dailinks would be cpu/codec/platform dais. |
| |
| - link-name: |
| Usage: required |
| Value type: <string> |
| Definition: User friendly name for dai link |
| |
| = CPU, PLATFORM, CODEC dais subnodes |
| - cpu: |
| Usage: required |
| Value type: <subnode> |
| Definition: cpu dai sub-node |
| |
| - codec: |
| Usage: Optional |
| Value type: <subnode> |
| Definition: codec dai sub-node |
| |
| - platform: |
| Usage: Optional |
| Value type: <subnode> |
| Definition: platform dai sub-node |
| |
| - sound-dai: |
| Usage: required |
| Value type: <phandle with arguments> |
| Definition: dai phandle/s and port of CPU/CODEC/PLATFORM node. |
| |
| Example: |
| |
| audio { |
| compatible = "qcom,apq8096-sndcard"; |
| qcom,model = "DB820c"; |
| |
| mm1-dai-link { |
| link-name = "MultiMedia1"; |
| cpu { |
| sound-dai = <&q6asmdai MSM_FRONTEND_DAI_MULTIMEDIA1>; |
| }; |
| }; |
| |
| hdmi-dai-link { |
| link-name = "HDMI Playback"; |
| cpu { |
| sound-dai = <&q6afe HDMI_RX>; |
| }; |
| |
| platform { |
| sound-dai = <&q6adm>; |
| }; |
| |
| codec { |
| sound-dai = <&hdmi 0>; |
| }; |
| }; |
| }; |
